  2. 1. Oscillatory Ca2+ signaling in glucose-stimulated murine pancreatic β-cells : Modulation by amino acids, glucagon, caffeine and ryanodine

    Author : Meftun Ahmed; Per Lindström; Uppsala universitet; []

    Abstract : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. READ MORE

  4. 2. Roles of voltage-gated Ca2+ channel subunits in pancreatic β cells

    Author : Abdulla S. Kazim; Diabetes - öpatofysiologi; []
    Keywords : diabetes; Type 2 diabetes T2D ; Ca2 ; Ca2 channels; subunits;

    Abstract : Hallmarks of type 2 diabetes (T2D) include elevated blood glucose and free fatty acids (FFAs) as a result of impaired β cell insulin secretion and decreased β cell mass. The glucose-stimulated insulin secretion (GSIS) in β cells is triggered by depolarization-evoked Ca2+ entry through voltage-gated Ca2+ (CaV) channels. READ MORE

  5. 3. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    Author : Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    Abstract : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. READ MORE

  7. 5. Effects of Ca2+, microRNAs, and rosuvastatin on insulin-secreting beta cell function

    Author : Vishal Ashok Salunkhe; Diabetes - öcellsexocytos; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 diabetes; exocytosis; Ca2 ; miR-375; miR-335; rosuvastatin; voltage-gated Na channels; STXBP1; SNAP25; SYT11; glucose homeostasis; beta cell function;

    Abstract : Type 2 diabetes (T2D) is a condition of high blood glucose levels due to insulin resistance and defective insulin secretion. Impaired insulin secretion plays a major role in the pathophysiology of T2D, it is mainly attributed to beta cell function i.e. failure to secrete insulin or reduced beta cell mass. READ MORE
